what does the inside of the oil cap look like.isuzu are great motors.most likey a slight leak in the radiator and someone used a barrs leak type product .throw some motorup in the engine oil to be on the safe side.if you need a new radiator,the wrecker on morrin rd is good.hes got a store on trademe

Look for a whiteish gunk under the oil cap and post the results the grey and white gunk could mean trouble.

THank you all sooo much for sharing your knowledge with a "motorhome virgin". Thanks next to normal, I will keep that in mind. Owene. I traded the vehicle from a car dealer who could tell me nothing about it.The vehicle belonged to an elderly gent for 15 years.The elderly man now has dementia. THe motor has only done 98000ks.It has only done 54000k while in NZ (since 1996)I suspect that the it has sat for awhile as I found mouse drops in the cupboard and that"musty" smell. I have driven over 1200kms on it without it needed oil or water. It gets a bit warm going uphill, but the gage drops again straight away (Never gets hot). I just noticed the grey gunky stuff yesterday. Its like a soft grey clay colour. I think it smells like some sort of product - Anti-freeze!All comments offered here are most gratefully accepted and appreciated. THank you all again. :)

Could also mean someone accidentally put some oil in the wrong hole!
Does happen and is a bitch to get cleaned out completly.
